I would put it this way.

IMHO "fonctionnelle" doesn't mean much here - and it is not clear in this phrase that it is necessarily a management position.

Possibly not the greatest headline answer :-)

the point is that "fonctionnelle" is as opposed to "technique". In other words, that this individual, in addition to the IT skills, is willing and able to understand the functional need(s) that the IT is used to serve, what the users use the system/application/technology to achieve.

As I have pointed out once or twice in questions about "metier", French IT depts were traditional very seperate from the functional depts they were supposed to be helping. The fact that an analyst programmer or project mgr might actually visit the users, find out what they do and what they need, was a radical development.

Hence, having this ability to get "involved" with the business/functional depts is seen (as it is elsewhere) as an asset (as against computer geeks who can do everything technically possible but are unable to speak to anyone in anything but Clingon!)

and that's what they're getting at here - I leave it to you to decide how best to express it :-)

Have done the whole sentence for you dv, as so much of the legwork had already been done by Charlie.

Good listening and interpersonal skills combined with a strong involvement in the company's activities will enable you to succeed in this position.
